ROLLER SIDE BEARING.

Specification 0f Letters Patentlatentcd Feb. .l-t, |91 l, Appncanon filed June s, 1910. seran No. 5653015..

To will whom 'it may concern:

Be it known that l, JonN ll". OCoNNoIi, a citizen of the United States, residing in Chicago, in the county of.Cook and State ot' Illinois, have inventedV a new and useful In1 provementin Roller Side Bearings, of which the following is a specification.

My invention relates to improvements in roller side bearings for railway cars. i

iln roller eide bearings for railway cars, ditliculty has heretofore been experienced in practical operation from the t'act that owing to the deflection ot" the boleters under load, the Contact of the anti-friction roller with the bearing plates frequently comes ohioliy at one end of the roller, thus giving a very inadequate bearing contact area between the roller and'plate or platee, and causing friction and deetructive wear of the parte.

The object of my invention is to provide a roller Side bearing of strong, simple, etlicient and durable construction by which thieobjection or dilliculty will be obviated or overcome.

My invention consists in the nieans l ein ploy to practically accomplish this object. or result as .herein shown and described, and more particularly epeeitied'in the claims.

ln the accompanying drawing forming a partof this specification, Figure 'l a eide elevation of car truck and body holsters provided with roller' eide bearinge en'ibodying my invention. Fig'. 2 is a detail, centrah vertical section in the piane oil the of the unti-friction roller. Fig. 3 le a vert-ical cross section on line 3---3 ot-Fio'. i2 and llio.-

l a horizontal sect-ion online fw-li ot' Fig.

ln the drawing, l represents the bodyI bol eter ol a. car, 2 the truck bolster, 3 the lower bolster hearing plate secured to the truck bolster, et the upper bolster bearing plate secured to the body bolster, 5 an ziiit-i-fiicti0n roller and 6 euiipleniental rocker or adjustable hearing plate interposed between the two bolster'lacaring platee and against which Itho anti-friction roller directly acte Vso thi'it .by its rocking or autorita-tio ,adjuntinent in respect to the bolster bearing;l plates,

the antiffriotion roller may automatically adjust or adapt-:itself to tho tread face of the bol-.Liter bearing plate with which it directly contacte, and thus "compensate 'tor any in* for; in res peet l to plate by'yvliiclyitl 4s carried, to the extent.

oqualitiee due to deflection ot the bolsteri under load or other causes.

The lower or truck bolster bearing plate B bolts or rivets 7 which pase'` through ite base liango 8, and 1t 1e provided witlran extended tread face J curved about. the icing bolt as a center and projecting to each std e of thc truc; bolster 2.

The upper or bolster bearing plated is rigidly Secured to the body bolster 'l by boite or rircls l() which poes through its flange il, and it ie provided with integral depending llangee or lugo' l2 to receive between them the supplemental rocker or adjustable bearing` plate (i, and also 'with curi-'cd bearingl 'faces 13 l'or engagement with the corre- Spendingl bearing' 'facce lt ot' the supple mental bearing' plate ti.

.lhe Supplemental or rocker bearing plate or traine (3 ieinovablyor pivot-ally Secured to one ot' the bolster bearingplatee7 preferably the upper or body bolster bearing plate, by pivot pine l5, preferably having conical ends lli to enter tht` conil 'shaped pivot holes l? in the supplemental bearing` plate (i, and provided 'with Screw threads lo for engage'- iuent with the corroepoinliilg Screw threadsin the llangcs or 'hure ot the fixed bearing.

plate el. The ,La :rcw pivot pine l5 are also furnished with split licys 1 9 to lock them in position.

The anti-'friction roller 5 may be of any suitable torni` that illustrated in the drawing' boing' acylindrical one instead of a conical one, and lirovideil with trunuions i2() at. cach end. preferably integral witlieaeh other, and in a ee'iarate piece Jrointhe roller. The trunnions 20 litin and engage the supplement-.al or intermediate rocker bearing; plate (3 which is furnished with suitable bearings 21or'cngagemcnt with the trunnions Z0, The trunnion member or Vis rigidly secured to the truck bolster by 'Sii shaft 20 is preferably fixed to the roller 5 by a transverse rivet 22.

.As the anti-friction roller has its directy bearing or engagement against the supplemental bearing plate (i, and as this suppleinental bearing plate 6 -iiiay automatically the fixedlbeariig neceseary toenable Ithe roller to properly and evenly oontacrtn throughout its length' with the other bolster bearingplate, any' deflection of the holsters' and ot' the'bearing plates carried thereby is automatically coin- 'pensated for, thus insuring proper action of g the anti-friction roller from end to end and .preventinr undue friction, cutting and wear inci ent to an unequal bearing orcontact of the antiiriction roller with the treads or bearing surfaces of the bearing' plates.

As the bolster bearing plate 4 and sup-A plemental or rocker bearing plate 6 have shearing or other strain and is not required Vto perform a load supporting function.

interengaging load supporting surfaces or bearings 13, 14 independent of the pivotal connection l5 between these parts, the piv-4 otal connection 15 is entirely relieved from As in my invention, 'the supplemental rocker bearing plate interposed between the main or bolster bearing plates 3, 4, is free to roel: or tilt, the 'roller is'free to adjust itself to any axial line of rotation that may be required, and the bearing .plates 3, 4 can thus be fixed to bolsters of varying inclinations of surface to which the bearing platesv f3, 4 are directly applied, without necessi- ,ating any change in the patterns off the pearing plates v3,4 to meet any variations in angle of the bolsters, whether such varia- 'tion be due to' inaccuracies of manufacture, .-'hanges of design, deflections while in use or to errors in molding the castings.

Al. In a rocker side bearing for railway cars, the combination with a body bolster and a truck bolster and bolster bearing plates rigidly secured thereto, of a supplemental rocker bearing plate mounted to tilt about an axis'transverse to the bolster and interposed between said bolster bearing plates, and an anti-friction roller interposed between said supplemental rocker bearing' plate'and one of said bolster bearlied.

. ing plates land extending -across said bearing plates and journaled at its ends in said rocker bearing plate, substantially as specia 2. The combination withj upper.; and lower bolster bearing plates, ofa supplemental rocker bearing plate niounted to tilt about an axis transverse to the bolster and an anti-friction roller interposed between said rocker beaping plate and one of said bolster bearing" lates and extending across said bearing p ates and journaled atits ends iny said rocker bearing plate, substantiallv as specified. f*

3. The combantion .with upper and lower bolsterl bearing plates, of a supplemental roclrer bearing plate mounted to tilt about an axis transverse to the bolster and an anti-friction roller interposed between said rockerbearing plate and' one of said bolster bearing plates and extending across said bearing plates and journaled' at .its ends in said rocker bearing plate, the axis about which said supplemental bearing plate tilts being transverse to theaxis of the anti-friction roller, substantially as specitied.

4, The combination with upper and lower bolster bearing plates, of a suppleand having curved contacting load sustaining bearing faces independent of the pivotal connection to relieve said pivotal connection of the load, and an anti-friction roller interposed between said supplemental bearing plate and the other bolster bearing plate, substantially as specified.

6. The 'combination with upper and lower bolster bearing plates, of a supplemental' rocker bearing plate pivotally secured to one of said bolster bearing plates, and having curved contacting load sustain-- ing bearing faces independent of the pivotal connection to relieve said pivotal connection of the load, and an anti-friction roller interposed between said supplemental bearing plate and the other bolster bearing plate, the axis of said roller being transverse to the axis of said supplemental orlrer bearing plate, substantially as speci- 1e ,l v
